This series solves some outstanding bugs in the dshow device, implements
get_device_list so that `ffmpeg -sources dshow` works and adds logic to
select a video format with extended color information (color range,
space, etc) if exposed by the device.

v7 adresses review comments from Hendrik on patch 11/12.

This is a new version of part of the patch series in
addressing review comments i got there. They have been previously OK'ed
offlist by the dshow maintainer Roger Pack. Specifically, these patches
are the enhancements that should be uncontroversial as they do not touch
the avformat API. Once pushed, i'll re-send the other more controversial
patches on top of these.
